i think i need to get myself a rev counter soon. is there anyway to just get the dash with a rev counter from the scrappy and wire it up to that?

Martin mate, i would reccomend you grab yourself a 5sp box. Used to have the 1.2 8v with 5 speed, and it was always a little better in 5th gear. Gearbox is F10 and can be found in both Nova's and Corsa's, although the 4 speed was the only F10 in Nova, and Corsa Merit. All other 1.2 8v's got the 5 speed.
However the 5th gear is an overdrive gear and will not increase top speed. that is obtained in 4th gear at 96mph
If you do a lot of motorway miles, get the 5speed, you can pick them up for next to nothing. And my car was quite happy to sit on the outside lane of the motorway at 85-90.

Insurance doesnt even have to know, its the same as your gearbox going bang and you only being able to source a 5 speed box, it really doesnt matter.

O right i see.

Is it just a case of taking the old one off and replacing it with the "new" one?
